- The ECLUSE tunnel connects the steam network across the Scheldt to enhance industrial symbiosis.
- Evonik will reduce CO2 emissions by 100,000 to 150,000 tons annually by using ECLUSE steam.
- The tunnel project involves Indaver, FINEG, SLECO, Port of Antwerp-Bruges, and Water-Link.
- ECLUSE steam is 50% green, derived from biogenic waste processed at Doel.
Project Overview
The ECLUSE tunnel project aims to connect the steam network across the Scheldt, facilitating the transport of recovered energy in the form of steam from waste-to-energy facilities to industrial users. This initiative is a collaboration between private and public partners, including Indaver, FINEG, SLECO, Maatschappij Linkerscheldeoever, Port of Antwerp-Bruges, and Water-Link, with support from the Flemish government.
Energy Efficiency
The steam network currently supplies five companies in Waaslandhaven, enhancing energy efficiency by using steam directly in chemical processes. By connecting Evonik to this network, the proportion of directly utilized heat increases, offering higher energy efficiency compared to electricity conversion.
Environmental Impact
Evonik's connection to the ECLUSE network will significantly reduce its fossil fuel consumption, saving natural gas equivalent to the annual use of over 38,000 households. This transition will avoid 100,000 to 150,000 tons of CO2 emissions annually. Approximately 50% of the steam is considered green heat, derived from biogenic waste.
Future Prospects
After Evonik, other companies on the right bank can also connect to the steam network. The tunnel will accommodate additional pipelines, addressing the need for more pipeline capacity under the Scheldt and facilitating growth in the Antwerp industrial cluster. Future opportunities for further cascading of heat are also anticipated.
